PURPOSE: To provide a road rivet having a reflexive reflection section where metal thin films are laminated out its back, and does not corrode even when used for a long term.

CONSTITUTION: A reflexive reflection section 3 is formed on a pair of mutually opposite faces of the oblique side of an outer shell body 1 being conical or truncated pyramid-shaped, and metal thin films 5 formed of an aluminum thin film are laminated on the back of the reflexive reflection section 3, and unhardened filler is injected into the inside of a cavity and hardened to form a core body 8. A partitioning wall 6 which is made of a rigid material and watertightly separates the metal thin film 5 of the reflexive reflection section 3 from the core body 8 is provided between them to separate the metal thin film 5 from the core body 8 for preventing the metal thin film 5 from corrosion caused by hardener included in filler being the forming material of the core body 8.
